Engine & Transmission Mounting - 2002 Cadillac Seville (gmpartsgiant.com)

 

Welcome Aboard !!! Which Seville - SLS or STS? it makes BIG differences in much advice and repair advice offered.

Google Search

Front center mount is a common problem and covered in great detail in here, Deville, and Engines Northstar.

 

I have the STS model, what will be different?

 

In link in Post 2 on parts, it says fitment code option. On option tag on your vehicle will show the build code installed on your vehicle. Match that with part you're wanting in the link in post 2.
I broke parts down to STS in this link. It shows part numbers you need so you can do a search with those numbers to try and find online hopefully when parts are discontinued as shown.

Thank you for all your help! Also, if you have any recommendations for aftermarket struts. Mine are starting to make noises.

 

With prejudice - the F55 MRC. It's quicker, more adaptable, infinitely variable in its control rates. The system has gone on to become the active suspension control for many other vehicles and equipments worldwide.

CVRSS (Constantly Variable Road Sensing Suspension) used a system of sensors to adjust suspension damping by changing to one of two fixed orifice sizes in the struts/shocks which altered fluid flow rates during maneuvering events. MRC (Magnetic Ride Control) uses a fixed orifice in the strut/shock piston that is surrounded by a powerful electromagnet. The fluid is a mixture of molecular iron and hydraulic oil which, as it passes through the ever-changing magnetic field, can go from a 10W oil to thick paste in less than .001 second, thus drastically altering damping rates. The MRC system is fed by over a dozen sensors that constantly monitor and adjust suspension controls in real time.

The several suspension control systems are mutually exclusive and non-interchangeable.

One of our FWD Northstar suspension experts is not far north of you - basscatt - see his work in here, Deville, and Northstar.

Thanks for the info! Have you done or seen anyone do an upper dog bone mount?

 

Several members have fabricated their own version of the discontinued Eldorado dogbones. About 10 years ago, several threads in Seville and Deville.

Yes, the front cross-brace is plenty strong - the Eldorado uses it for its dogbone mounts. Max torque of 300 pounds at WOT - and you can lift the entire front of the car with it.

Some dogbone parts in the 2000 - 2002 Eldorado sections of www.gmpartsgiant.com or www.gmpartsdirect.com - but not a direct fir for Seville.
